Abstract: An electron gun includes plural aligned charged grids each having an aperture (in a monochrome CRT) or plural apertures (in a color CRT) through which an electron beam (or beams) is directed. The beams emitted by a cathode sequentially transit a beam forming region (BFR), a dynamic focus lens and a main focus lens prior to being incident on the CRT's display screen. The electron beam tends to expand in diameter in the direction of the CRT's display screen. This results in an increase in the focusing effect on the electron beam of the electron gun's grids in proceeding from the BFR toward the display screen where the beam passing apertures in the various grids are of the same size. To increase electron beam focusing sensitivity while reducing the beam's dynamic focus voltage, the beam passing apertures in the gun's dynamic focus lens are provided with progressively reduced size in proceeding toward the electron gun's cathode.

Abstract: A partial oxidation reformer comprising a longitudinally extending chamber having a methanol, water and an air inlet and an outlet. An igniter mechanism is near the inlets for igniting a mixture of methanol and air, while a partial oxidation catalyst in the chamber is spaced from the inlets and converts methanol and oxygen to carbon dioxide and hydrogen. Controlling the oxygen to methanol mole ratio provides continuous slightly exothermic partial oxidation reactions of methanol and air producing hydrogen gas. The liquid is preferably injected in droplets having diameters less than 100 micrometers. The reformer is useful in a propulsion system for a vehicle which supplies a hydrogen-containing gas to the negative electrode of a fuel cell.

Abstract: A position latch device is used with a clamp of the type including a pair of pivotally coupled gripping members respectively defining gripping jaws at one end and first and second handle portions at the opposite end. The gripping members are operable between a latched open-jaw condition and a non-latched closed-jaw condition. The position latch device includes a resilient spring extending from the first handle portion toward the second handle portion in an arcuate manner and deflectable by the second handle portion as the gripping members move from the closed-jaw condition to the open jaw condition so as to exert on the second handle portion a force component in a direction opposite the direction of movement of the second handle portion. The spring has a fixed end connected to the first handle portion and a free end.
